Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

4.8K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Radius

5.2K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Ankle Joint01:10

Ankle Joint

3.1K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Muscles that Move the Arm01:31

Muscles that Move the Arm

5.0K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

    Area of Science:

    • Orthopedic surgery
    • Sports medicine
    • Hand and wrist injuries

    Background:

    • Scapholunate ligament injuries are a subset of wrist sprains.
    • Diagnosis can be challenging due to subtle presentations.
    • Potential for long-term joint dysfunction exists.

    Purpose of the Study:

    • To highlight the diagnostic challenges of scapholunate ligament sprains.
    • To emphasize the importance of timely diagnosis and treatment.
    • To discuss the sequelae of untreated severe injuries.

    Main Methods:

    • Clinical examination for localized pain.
    • Radiographic assessment for abnormalities in severe cases.
    • Review of patient outcomes based on treatment.

    Main Results:

    • Characteristic localized pain is a key diagnostic indicator.
    • Severe ruptures often present with distinct radiographic findings.
    • Minor sprains typically resolve without lasting issues.

    Conclusions:

    • Early and accurate diagnosis of scapholunate ligament sprains is essential.
    • Surgical intervention for severe ligament complex ruptures can prevent post-traumatic arthritis.
    • Untreated severe injuries may lead to chronic wrist pain and dysfunction.
